A 46-year-old man was sent to hospital in critical condition Thursday after he was pinned between two vehicles following a collision in the Saint-Laurent borough, Montreal police say. Police got a 911 call at around 5 p.m. and responded to the scene, near the intersection of Henri-Bourassa Boulevard West and Thimens Street. According to preliminary reports, the man was working on a manhole on Henri-Bourassa Boulevard when he was struck by a car, driven by a 67-year-old man. “For reasons that remain unclear, the driver reportedly did not brake or change course, hitting the worker head-on and trapping him between this car and a van,” said police spokesperson Manuel Couture. The worker suffered serious, life-threatening injuries. Couture said alcohol and speed are not believed to be factors in the collision. Officers are speaking to witnesses and looking for surveillance camera footage as they continue their investigation.
